“…Although urban adapters take advantage of human‐provided resources similarly to urban exploiters, they do not strictly depend on them (Fischer et al., 2015; McKinney, 2006); thus, urban adapters provide an interesting opportunity to assess urban‐driven evolutionary change in free‐living populations. Importantly, even though urban adapters belong to a wide range of taxa (including: insects—Kaiser, Merckx, & Van Dyck, 2018, mammals—Harris, Munshi‐South, Obergfell, & O’Neill, 2013, amphibians—Stolyar, Loumbourdis, Falfushinska, & Romanchuk, 2008, reptiles—Winchell, Reynolds, Prado‐Irwin, Puente‐Rolón, & Revell, 2016; Winchell, Maayan, Fredette, & Revell, 2018), birds are an excellent model system to explore urbanization‐related shifts in evolutionary ecology (Chamberlain et al., 2009; Marzluff, 2017). Several studies emphasized important differences in the reproductive strategies adopted by rural and urban avian populations; thus, birds inhabiting cities often exhibit earlier laying dates, smaller clutches and reduced brood sizes compared to their rural counterparts (Chamberlain et al., 2009; de Satgé et al., 2019).…”
